tikzDevice: R Graphics Output in LaTeX Format

Provides a graphics output device for R that records plots
in a LaTeX-friendly format. The device transforms plotting
commands issued by R functions into LaTeX code blocks. When
included in a LaTeX document, these blocks are interpreted with
the help of 'TikZ'—a graphics package for TeX and friends
written by Till Tantau. Using the 'tikzDevice', the text of R
plots can contain LaTeX commands such as mathematical formula.
The device also allows arbitrary LaTeX code to be inserted into
the output stream.
